Leatherwood
Leatherwood (also called Moosewood, Wicopy, and Ropebark), a shrub that grows wild in damp places in Canada and the northern United States. It is also cultivated in gardens. The leatherwood grows as tall as six feet (1.8 m) and bears oval leaves, small clusters of yellow flowers, and reddish stone fruits resembling tiny cherries. The wood is soft and brittle, but the bark is extremely tough and was used frequently to make twine by Indians and pioneers.
Leatherwood is Dirca palustris of the family Thymelaeaceae.
